The recently released photos of Cha In-pyo and Shin Ae-ra are reminiscent of the youthful days of a couple in their 20s. The two shots, with their deep affectionate eyes and close contact with each other, belied the fact that they have been married for 31 years, surprising many people. In particular, the sight of Cha In-pyo wrapping his arms around Shin Ae-ra's waist or Shin Ae-ra naturally being held in his arms is not simply a show-off, but clearly shows the deep trust and intimacy that has been built up over a long period of time. The public does not hesitate to label them as a ‘middle-aged wannabe couple’ when they see this, and their appearance projects an ideal form of marriage. Even though they are a couple with mature family members who have a daughter-in-law, the fact that they still do not lose excitement in their relationship is a great example to many people.

This couple's relationship is by no means maintained simply by luck. Shin Ae-ra revealed that 15 years ago, she used personality type tests such as MBTI to reduce marital fights. This proves that it was an active communication effort to acknowledge and understand each other's differences. Since a couple is a process in which strangers who grew up in different environments meet and build one world, conflict is inevitable. However, instead of avoiding or suppressing conflict, they tried to understand each other's language using scientific and rational methods. This ‘relationship intelligence’ is the core driving force that allowed two people to stay by each other’s side for 31 long years, and it can be said to be an attitude that modern couples must learn.

Cha In-pyo recently provided deep insight into his human relations theory. He emphasized a simple attitude toward life that is not obsessed with personal connections through the message, “Don’t hold on to it by force.” This philosophy also applies to marital relationships. The attitude of respecting each other's individuality independently, rather than trying to own or confine one another to one's own framework, is what keeps the relationship healthy. Just as he said that he reflected on himself while going through a period when he did not need personal connections, it is analyzed that the process of sorting out external relationships and building internal strength actually made the closest relationship, that of a married couple, more transparent and healthy.

This couple’s daily life is filled with small events, such as a T-shirt with a heavy confession saying, ‘You are mine.’ It symbolically shows that although the world has changed and their environment has changed over the past 30 years, their confidence in each other has not changed. When many people complained of boredom within the institution of marriage, they did not give the feeling of boredom a chance to penetrate through small expressions and constant communication in their daily lives. The images of these people showing off their unwavering affection are not simply entertainment industry gossip, but are read as a narrative that proves how valuable and beautiful it is to love one person for a long time.
